To ttl/Z whom it may concern.- Y

Be it known that I, JOHN B. WARING, a citizen of the United ark, in thecounty of Essex and State 0f New Jersey, have invented certain new anduseful Improvements in Devices for Cleaning Ships, of which thefollowing is a specification.

My invention relates to devices for cleaning ships hulls. v

I will describe a device embodying my invention and then point out thenovel features thereof in the claims.

ln the accompanying drawings, Figure l is a top view of a device forcleaning ships hulls embodying my invention. Fig. 2 is a bottom view ofthe device shown in Fig. l. a longitudinal sectional View. Fig. 4 is atransverse sectional view. Figs. 5, 6, and 7 are detail views of severalparts comprised in the device.

Similar letters of reference designate corresponding parts in all of theviews.

A represents a suitable casing, in which the motor and mechanismforoperating the cleaning devices are contained. It is of any desiredshape and may be made vup in any desired manner. Preferably the casingwill have an open bottom. The wall of this opening is provided with aflexible strip d., which extends beyond the edge thereof. This strip ispreferably held in position by an angleiron ct, which may form part ofthe casing. l have shown the strip as being wedge-shaped incross-section, though the strip may have anyY other form incross-section. One edge of the strip along one side of the casing isheld up by a metallic piece 61,3, carried by the casing. This is toprevent the strip from being bent or turned under when the device ismoved over the vessels hull. The purpose of this strip is to make areasonablytight joint between the casing and the vessels hull when thedevice is being operated to clean the hull. Preferably the strip a is soarranged on the casing about the opening thereof that the strip willtravel over the cleaned surface of the vessels hull. Air or water, orboth, are exhausted from the casing by any suitable device through anopening in the casing, thus enabling the exterior pres- Fig. 3 isAStates, residing at Newsure of air or Water, or both, to hold the casingagainst the ships hull.

Extending longitudinally of the casing A are two bars or other supportsb'. 4They are held in the casing by bolts, which pass through them, andlugs b2, that are secured to the casing. Extending between these twosupports are a number of integral yokes b3. ports b and the yokes b3 mayconstitute a frame to support the operating parts of the cleaningdevices. Theyokes in connection with cap-plates b4, form bearings fortwo shafts O O'.' The central yoke b3 is provided with a flange o, towhich a fiange 57 of an engine D is connected. The engine D ispreferably a rotary one of any desired type and operated by either air,electricity, or steam. d represents the inlet for the engine, and d' theexhaust therefor. The shaft d2 of the engine is provided at each of itsends with a pinion d3. These pinions d3 mesh with intermediate gearsdl,and the gears d4 in turn mesh with driving-gears d5, carried by theshafts O O'. The shafts of the gears d4 are carried in standards E. (SeeFig. 7.) These standards are held in position by the shafts C, C, andd2, suitable openings e and e' being provided in the standards throughwhich these shafts extend and loosely turn.

F- represen ts cleaning-heads which are journaled in the forked ends fof reciprocating rods f'. Each head consists of a plurality ofscraping-blades f2, radially arranged, and on each blade f2protuberances f3 are provided, which are formed by cutting the blade andalternately bending outward the metal between the cuts. The purpose ofthese protuberances is to prevent the blades scraping off paint. Theforked ends f are hinged at f4 to the ends of the rods f', and they areheld against the surface to be scraped by springs f5.

The rods f' are adapted to be reciprocated, and they are guided bysleeves g, secured to the casing A, and sleeves g', carried by thesupport b. As shown, each rod is made in sections in order that it canbe conveniently assembled and placed in position in the device.

The rods f are reciprocated by means of The supv IOO ` connection withone end of said eccentrics c, carried by the shafts C C. The eccentricsare arranged on the shafts preferably in advance of one another in orderthat the rods fand cleaning-heads may be moved successively. Theconnection between each eccentric and rodf may be made by means of astrap c', which surrounds the eccentric, and a link c2, connecting thestrap with the rod.

In operating the device it is lowered into the water and moved againstthe ships hull and the exhausting device (not shown) set in operation toexhaust air and Waterfrom Within the casing to permit the exterior wateror air pressure to hold the casing against the hull. rlhe rotary engineis then set in operation to reciprocate the cleaners, and as thecleaners are operated the device is moved over lthe hull. As a bladepasses over the plates of the hull and engages with the edge of anoverlapping plate it is turned on its bearing, and thus brings a newblade against the next plate.

Instead of cleaningblades brushes may be substitn ted; also, instead ofreciprocating the brushes or blades they may be rotated.

What I claim as my invention is l. In a device for cleaning ship-hulls,the combination ofa casing, a shaft suitably journaled in said casing, amotor for rotating said shaft, a rod operated from said shaft, and arotatable cleaning device having a hinged rod.

2. In a device for cleaning ship-hulls, the combination of a casing, ashaft suitably journaled in said casing, a motor for rotatingsaid shaft,a cleaning device, comprising a plurality of blades, rotatably mountedin the end of a rod, the said rod, and means for reciprocating said rodfrom said shaft.

3. In a device for cleaning ship-hulls, the

combination of a casing having an open side which is against the hulland which casing is adapted to be held thereagainst by exteriorpressure, means for providing a tightjoint between said casing and theships hull, a motor and driving-shaft Within said casing, and aplurality of cleaning devices without said casing which are operatedfrom said shaft.

4. In a device for cleaning ship-hulls, the combination of a casinghaving an open side which is against the hull, and which casing is heldagainst the hull by exterior pressure, means for providing a tight jointbetween said casing and the hull, a motor and operating-shaft within thecasing, a rod or rods adapted to be reciprocated from said shaft, and acleaning device or devices each having blades, rotatably mounted in saidrod or rods.

5. In a device for cleaning the hull of a -ship, the combination of amotor, and a plurality of rods adapted to be reciprocated by said motorand a cleaning-head rotatably mounted in each rod, said head com prisinga plurality of radially-extending blades.

6. A cleaning-head comprising a plurality of radially-extending bladesand protuberances on the ends of said blades.

7. The combination in a device for cleaning the hull of a ship, of amotor, rods operatively connected with said motor, and cleaning-heads,said heads heilig suitably journaled in the hinged and forked ends ofsaid rods.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
